I personally wasn't aware of it until a friend of mine told me about it.
So, what do you think of it?
Personally, I like the new design layout, but I'm disappointed over the lack of (other?) new features, especially considering tte fact that this is a new major version. And, also a bit disappointed over how short the max-length of the feedback message you can submit, is.
Nevertheless, I have a new browser and I like it better than the previous one .. althout the fewest of the FF plugins available actually support 4.0..
What about you guys, what do you think?
